Title: Adaptive quantizer
Inventor: NAGATA MICHIKO
IPC: H03M7/38
Filed: 1988-08-24
Abstract: PURPOSE:To attain a satisfactory quantizer adaptive control without depending on the type of an input signal by adapting to the type of an input signal and setting the adaptive speed of the quantizer. CONSTITUTION:A speed control parameter calculating circuit is composed of an estimation function 11, a leak integrator 12, a comparator 13 and a limiter 14. When an input is a sound signal, since a level fluctuation is severe, a quantizing value I becomes a smooth distribution over the wide range. On the other hand, when the input is a MODEM signal, since the level in the stationary condition is approximately constant, the distribution of the quantizing value I becomes steep with a certain value as a center. Then, by an estimation function 11 to display the difference in the distribution condition of the quantizing value of the sound signal and the MODEM signal, it can be known whether the input signal is the sound signal or the MODEM signal. Consequently, by using the estimation function 11, the speed control parameter can be applied and set to the input signal. Thus, the optimum adaptive quantization can be executed for the input signal.

Title: Feedback type noise reducer
Inventor: MIZUTA MASASHI
IPC: H04N9/77
Filed: 1986-09-04
Abstract: PURPOSE:To eliminate noise in response to the characteristic of a luminance signal and a chrominance signal by varying feedback quantity independently as to each of the luminance and chrominance signal in an input video signal. CONSTITUTION:A video signal SV fed from an input terminal 1 and a signal fed from a synthesis circuit 12 are subtracted by a subtractor 2. That is, the noise component of the luminance signal and chrominance carrier signal is subtracted from the signal SV and a video signal SV* whose noise component is subtracted is outputted at an output terminal 4. Through the constitution above, the characteristic of limiters 9Y, 9C of the luminance signal system and carrier signal system and gain adjustment circuits 10Y, 10C is made different and the feedback quantity of the chrominance carrier signal is made larger than that of the luminance signal. Thus, the reduction rate in the noise component of the chromiance carrier signal is higher than the reduction rate of that of the luminance signal. Thus, the noise rejection in response to the brightness is applied.

Title: Laser diode pumping solid-state laser
Inventor: NOZAKI NOBUHARU
IPC: G02F1/37
Filed: 1990-08-06
Abstract: PURPOSE:To improve the wavelength transducing and energy utilizing efficiencies of the title laser and, at the same time, to make low-threshold oscillation possible by fetching the second harmonic of an oscillated laser beam or the wavelength-transduced wave of the sum frequency, etc., of a semiconductor laser beam and the oscillated laser beam. CONSTITUTION:A laser beam 18 is transduced to 172 in wavelength, namely, to the second harmonic 18' in a laser medium and, at the same time, in an optical waveguide 15 having a waveform transducing function. The phase matching is made between the waveguide mode of the laser beam 18 in the waveguide 15 which is a basic wave and the radiation mode of the harmonic 18' in a substrate 14. Since the output-side end face 13b of an optical waveguide element 13 is coated 16b, the harmonic 18' can be fetched efficiently from the element 13. It is preferable to form a coating 16a so that the harmonic 18' can be reflected well and the coating 16b so that part of the harmonic 18' can be transmitted and to make the harmonic 18' to resonate between both end faces 13a and 13b of the element 13. Therefore, high-strength harmonic 18' can be fetched.

Title: Frequency converting circuit
Inventor: OKAZAKI MITSUYA
IPC: H03H7/01
Filed: 1984-10-04
Abstract: PURPOSE:To prevent a beat disturbance within the band from taking place by providing a resistive BPF having a resistance value independently of a frequency to an output terminal of a mixer. CONSTITUTION:An input impedance has a resistance value in viewing a BPF10 from the 1st mixer 2. In other words, in applying the 1st local oscillating frequency f1 and harmonics nf1 generated by the mixer 2 to the BPF10, the harmonics nf1 are not reflected from the BPF10 but consumed internally as a heat. Thus, no standing wave due to the reflection of the harmonics from the BPF10 is generated. Thus, no beat disturbance is caused in the band. Thus generation of beat disturbance in the band is prevented.

Filed: 1987-08-22
Abstract: PURPOSE:To form the optional density of subsampling suitable for the characteristic of a picture by performing variable density subsampling, by which it is controlled whether an original picture element signal is transmitted or not according to the size of a predictive error. CONSTITUTION:The predictive error from a means value/predicting circuit 4 is supplied to a predictive error deciding circuit 5. Threshold data 6 is supplied to the predictive error deciding circuit 5, and it is decided whether the predictive error is larger than the threshold data or not. A bit map, which comes to '0' when the predictive error is below the threshold, and comes to '1' when the predictive error is larger than the threshold, is generated in a bit map generating circuit 7. The bit map is stored in a picture element data bit map memory 1 through a data bus 2. In case of '0' is transmitted as the bit map, the original picture element signal is substituted by a mean value, and in the case that '1' is transmitted as the bit map, the original picture element signal is transmitted.

Filed: 1987-08-24
Abstract: PURPOSE:To realize the discrimination of a character written in small size and the character of normal size by reflecting the information of character size to a discrimination result in a postprocessing part. CONSTITUTION:The postprocessing part 5 is constituted by a character attribute decision part 5 and a recognition result decision part 6. The decision part 5 decides the character attribute which respective recognition objective characters are a big character or a small one based on the size of the recognition objective character images which a recognition candidate character obtained by a recognition part 3 among respective recognition objective character image obtained by a character segmenting part 2 becomes a specified character. The decision part 6 decides the recognition result from the recognition candidate character for the respective recognition objective character images obtained by the recognition part 3 by using the character attribute of the respective recognition objective character decided by the decision part 5. Thus, as the information of the character size is reflected to the recognition result, the character written in small size and the character of the normal size can be discriminated.
